Question

我一直在尝试在我的MVC5网站上使用Postal。当我在我的网页上托管一个子网站，即http://localhost/Subsite我收到错误

虚拟路径'/'映射到另一个应用程序，这是不允许的

我已将其调试到创建ControllerContext时未正确设置HttpContext。由于我从Hangfire运行Postal，因此HttpContext.Current始终为null。 Postal使用以下代码创建ContollerContext。

        ControllerContext CreateControllerContext()
    {
        // A dummy HttpContextBase that is enough to allow the view to be rendered.
        var httpContext = new HttpContextWrapper(
            new HttpContext(
                new HttpRequest("", UrlRoot(), ""),
                new HttpResponse(TextWriter.Null)
            )
        );
        var routeData = new RouteData();
        routeData.Values["controller"] = EmailViewDirectoryName;
        var requestContext = new RequestContext(httpContext, routeData);
        var stubController = new StubController();
        var controllerContext = new ControllerContext(requestContext, stubController);
        stubController.ControllerContext = controllerContext;
        return controllerContext;
    }

    string UrlRoot()
    {
        var httpContext = HttpContext.Current;
        if (httpContext == null)
        {
            return "http://localhost";
        }

        return httpContext.Request.Url.GetLeftPart(UriPartial.Authority) +
               httpContext.Request.ApplicationPath;
    }

如何指定UrlRoot，以便不是拉出默认的localhost来根据我的子网站提取它？

我按照http://docs.hangfire.io/en/latest/tutorials/send-email.html的说明发送了我的电子邮件。本教程中的方法如下

    public static void NotifyNewComment(int commentId)
{
// Prepare Postal classes to work outside of ASP.NET request
var viewsPath = Path.GetFullPath(HostingEnvironment.MapPath(@"~/Views/Emails"));
var engines = new ViewEngineCollection();
engines.Add(new FileSystemRazorViewEngine(viewsPath));

var emailService = new EmailService(engines);

// Get comment and send a notification.
using (var db = new MailerDbContext())
{
    var comment = db.Comments.Find(commentId);

    var email = new NewCommentEmail
    {
        To = "yourmail@example.com",
        UserName = comment.UserName,
        Comment = comment.Text
    };

    emailService.Send(email);
}
}

我发现问题是FileSystemRazorViewEngine没有被邮政使用。为了实现这一点，我必须确保FileSystemRazorViewEngine是可用的第一个引擎。然后我将其删除，因为我不希望它成为默认引擎。以下是我更新的方法。

    public static void NotifyNewComment(int commentId)
{
// Prepare Postal classes to work outside of ASP.NET request
var viewsPath = Path.GetFullPath(HostingEnvironment.MapPath(@"~/Views/Emails"));
var eng = new FileSystemRazorViewEngine(viewsPath));
ViewEngines.Engines.Insert(0, eng);

var emailService = new EmailService(engines);

// Get comment and send a notification.
using (var db = new MailerDbContext())
{
    var comment = db.Comments.Find(commentId);

    var email = new NewCommentEmail
    {
        To = "yourmail@example.com",
        UserName = comment.UserName,
        Comment = comment.Text
    };

    emailService.Send(email);
    ViewEngines.Engines.RemoveAt(0)
}
}

在子网站中使用Postal和Hangfire
